Question 719466
x= 	cost of	movie	ticket					
y=	cost of	dinner						
 								
2	x	+	1	y	=	65	.............1	
y-2x=15								
-2.00	x	+	1	y	=	15.00	.............2	
Eliminate	y							
multiply (1)by		-1						
Multiply (2) by		1						
-2.00	x		-1	y	=	-65.00		
-2.00	x	+	1	y	=	15.00		
Add the two equations								
-4.00	x				=	-50.00		
/	-4.00							
x	=	12.50						
plug value of			x	in (1)				
2.00	x	+	1.00	y	=	65.00		
25.00		+		y	=	65.00		
				y	=	65.00		-25
				y	=	40.00		
				y	=	40.00		
x=	12.50		cost of	movie	tickets			
y=	40.00		cost of	dinner	

2 tickets cost $25
dinner costs $40
